While some architects are out to create lofty skyscrapers, Polish firm Centrala is shooting for the world's narrowest home. The house will be wedged between two larger buildings, and will sit just 133 centimeters at its widest spot.

Israeli magical realist writer Etgar Keret commissioned this house, which Centrala plans to insert in a crack between 22 Chłodna St. and 74 Żelazna St. in Warsaw. Although Centrala describes the house as an art installation, it will contain a bathroom, bedroom, and kitchen, and the plan is for it to serve as a residence and studio for young creators. The team still has to jump through some bureaucratic hoops, but the plan is to open the house in June.
